Chapter 1 Calibration Notices
Calibration Interval
Regular calibration can ensure the performance specifications of DG5000. You are
recommended to calibrate the instrument at a one-year calibration interval. You can
choose a proper calibration interval according to your requirement of the
performance accuracy but the calibration interval can not exceed 2 years (otherwise,
the specifications can not be guaranteed).
You are recommended to perform a complete calibration at the calibration interval to
ensure that the instrument will remain within specifications before the next
calibration.
Calibration Safety
You need to input the correct password before calibration each time you want to
calibrate the instrument. The password is used to prevent accidental or unauthorized
calibration of the instrument.
Press Utility Test/Cal Secure Code, input the correct password
using the knob and direction keys. Then, users can press Secure to turn off the
calibration safety protection. At this time, press Manual Cal to enter the calibration
interface or press Preset to restore the calibration values to their default values.
The calibration password is “2010”. The password is stored in the non-volatile
memory and will not change at power-off or remote interface reset.
Note: please press Secure to turn on the calibration safety protection after finishing
the calibration to avoid the mis-operation.

RIGOL Chapter 1 Calibration Notices
1-2 DG5000 Calibration Guide
To Stop the Calibration
You can power off the instrument to stop the calibration at any time during the
calibration. The calibration data stored will not be cleared when the calibration is
stopped and you do not need to calibrate the items already calibrated again in the
next calibration.
CAUTION
If the calibration is stopped when the instrument is writing the new
calibration constants into the Flash, you may lose all the calibration
constants and you need to perform the calibration again.
To Acquire the Calibration Service
RIGOL does not recommend manual calibration by users. If calibration is required,
please contact RIGOL customer service department or the local distributor.
Recommended Test Devices
It is recommended that you use the test devices listed in the table below or other test
devices whose performance specifications satisfy the “Performance Requirement”
listed in the table below for calibration.

Test Notices
For optimum performance, all procedures should comply with the following
recommendations.
1) Make sure the environment temperature is stable and between 18℃and 28℃.
Ideally, the calibration should be performed at 23℃±1℃.
2) Make sure the environment relative humidity is less than 80％.
3) Make sure that the instrument has been warmed up for at least 30 minutes
before the calibration.
4) Keep the test cables as short as possible and make sure that the impedance of
the cable is consistent with the requirement.
